EJCRN Remote Sealed Gauge Pressure Transmitter
The remote seal gauge/absolute pressure transmitter is suitable to measure liquid, gas, or steam flow as well as liquid level, density, and pressure, output a 4 to 20 mA DC signal corresponding to the measured gauge/absolute pressure. Other key features include quick response, remote set-up using communications,self-diagnostics, and optional status output for pressure high/low alarm. The range Limits is 0—6kPa-25MPa, The flange’s working pressure are 1.6/4MPa,6.4MPa,10MPa,150psi,300psi or 600psi.
Operation Theory and Structure
remote seal gauge/absolute pressure transmitter are composed of series
gauge/absolute pressure transmitter and the welding installation remote seal flange. The operation theory
is the same as series gauge/absolute pressure transmitter (see series gauge/absolute pressure transmitter general specifications),
Only the pressure transmission path is different. The pressure loaded in the high or low side, pass from the isolation diaphragm and silicone oil in the flange to the sensor.
